They are real.  But they are irrelevant to the issue of lung cancer
correlations with measured indoor radon (unless a bias of the time of
measurement is claimed, in which case it would need to be consistent in
direction, i.e., consistently measured at times when moisture is
low/high affecting a consistent bias to the average). 

Even if this were the case, which was not claimed, to be significant to
Dr. Cohen's results, it would then have to correlate with increasing
radon concentration, and be VERY large to affect the results of Bernie
Cohen's analysis.
